Title: Improvements in or relating to electro-therapeutical apparatus
IPC: A61N1/32
Filed: 1946-10-21
Abstract: 623,054. Electro-therapeutical apparatus. SHOTTER, G. F., and RICH, A. I. Oct. 21, 1946, No. 31287. [Class 81 (ii)] Electro-therapeutical apparatus for passing a steady current of pre-determined value through bone or tissue of a patient irrespective of the resistance, particularly in electro-narcosis, comprises a transformer 1 having a core of low loss alloy with high permeability, carrying a primary winding 2 across which is applied substantially constant voltage, such as from public supply mains, with an impedance 10 in circuit. This impedance is high compared with the variation of that of the winding 2 over a pre-determined range of values of impedance of a patient placed between electrodes 6 connected to the secondary winding 3 of the transformer. The ratio of the number of turns on secondary winding 3 to those on primary winding 2 is large, and the iron circuit of the apparatus is adjusted so that at the lowest value of the impedance of the patient and with the optimum value of current in the secondary winding the flux density in the arm is at or near the lower end of the straight part of the magnetization curve. A voltage limiting device, such as a gas filter glowdischarge tube 8<SP>1</SP>, may be connected across the secondary winding or, as at 8, across a separate tertiary winding 4 on the transformer to limit the rise in voltage and protect against overheating in the event of a sudden increase in the resistance of the patient.

Title: Improvements in or relating to Methods of and Devices for Stabilising and Igniting Welding and Cutting Arcs
IPC: B23K9/067
Filed: 1968-07-03
Abstract: 1,172,957. Arc welding systems. LINDE A.G. 3 July, 1968 [4 July, 1967], No. 31667/68. Heading H2H. A method of re-ignition of the arc each time the welding A.C. voltage passes through zero or igniting an A.C. or D.C. welding arc utilizes current pulses generated by a surge discharge from a capacitor through a controllable semiconductor which is conductive for a period of between 0À8 to 20 microseconds. As shown a welding transformer 8 has its secondary connected across an electrode 3 and workpiece 2 through an adjustable inductor 9 and filter capacitor 10. An isolating transformer 11 connected to the same source 6 or any other source charges a capacitor 13 through a rectifier bridge 12, smoothing resistor 14 coupled with smoothing capacitors 16, 17 and charging choke 15. When a thyristor 20 is made conductive the capacitor 13 discharges through a setting resistor 18 and the primary of a pulse transformer 19 having its secondary connected to the electrode 3 and workpiece 2. The thyristor 20 is made conductive when a glow discharge tube 31 strikes on voltage rise in the secondary circuit of the welding transformer 8 which is connected through a transformer 29 to the tube 31 which is in series with a control pulse transformer 25 connected to the thyristor 20. The glow-discharge tube 31 may be replaced by a voltage regulator tube, a Zener diode, a transistor or a unijunction transistor. The pulse transformer 19 may be omitted and the discharge circuit of the capacitor 13 directly connected across the electrode and workpiece. A plurality of controllable semi-conductors may be used in place of the thyristor 20.
Patent GB-361541-A (GB)
Title: Improvements relating to slicing machines
IPC: B26D7/32
Filed: 1930-10-22
Abstract: 361,541. Slicing-machines. FITZPATRICK, H. D., 94, Hope Street, Glasgow. -(Berkel, C. F. M. van; 33, Boezemsingel, Rotterdam, Holland.) Oct. 22, 1930, No. 31693. [Class 28 (ii).] In a stacker for a slicing machine, the conveyer is accelerated from the position at which the slice is cut and impaled, to the slice discharge position where it rests before moving again at normal speed to the impaling position. This arrangement is particularly suitable for stackers wherein the discharge fly is mounted on the conveyer, the period of rest giving sufficient time for the fly to discharge the slice and return to its normal position. As shown, a rotary conveyer 35 has spikes 21 which are impaled in the slice as it is cut by the knife 12 and deflected by the slotted plate 22. The discharge fly 23 is pivoted by a pin 50 on the rotary conveyer 35 and is moved to strip the slices from the spikes 21 by a torsion spring coiled on the pin. It is normally held upright by a flexible connection, e.g. a chain, 54 and a rod 55 attached thereto, the rod 55 having a roller 56 at one end which engages a two part cam 57, 58, the upper part 57 being revoluble with a chain wheel 33 and the lower part 58 being stationary. The fixed cam 58 has a sharp drop at the slice discharge position and the roller is allowed to fall into this drop by the rotary cam 57 which immediately after restores the fly to its upright position. The conveyer 35 is fixed on a shaft 34 on which the chain wheel 33 is journalled, the wheel 33 being connected to the shaft by a lost motion device comprising a pin 45 projecting from shaft 34 into a slot 46 in the boss of the wheel 33. A crank arm 43 is fast with the shaft 34 and is connected by a link 42 with a lever 40 having a cam face which co-operates with a pin 44 on a disc 15 on the carriage-driving crank shaft 14. In operation, the wheel 33 is driven continuously and regularly by the crank shaft 14 and the chain 30 and, whilst the slice is being cut and impaled, the pin 45 engages the end 46a of the slot 46 whereby the conveyer 35 is driven at its normal speed. When the slice is impaled, the pin 44 engages the lever 40 and swings the arm 43 rapidly through an angle of substantially 180‹ causing an accelerated motion of the conveyer to the slice discharging position. During this accelerated movement, the pin 45 travels to the other end of the slot 46, so that the conveyer remains at rest in the discharge position until the wheel 33 overtakes it and moves it again to the impaling position. During the rest period, the fly discharges the slice and is restored to its upright position. The invention is applicable to power or hand machines, or machines driven partly by power and partly by hand. Also, the discharge fly may be separate from the conveyer. Gearing may replace the chain 30.

Title: Improvements in heat exchanger for an evaporator
IPC: B01D1/00
Filed: 1956-10-19
Abstract: <PICT:0824354/III/1> <PICT:0824354/III/2> In an evaporator, suitable for distilling sea water, which is provided with a heat-exchanger having a generally cylindrical, vertical-extending wall formed with deep longitudinal corrugations, the interior of the heat-exchanger is provided with a cylindrical skirt for guiding the heating-medium so that it flows rapidly down through the inner recesses formed by the corrugations, whereby efficient heat-transfer through the corrugated wall to the water surrounding the heat-exchanger is obtained.  In the embodiment shown, reference 22 indicates the heat-exchanger; it has corrugations with internal recesses 34 and external recesses 36.  The upper and lower ends of the corrugations are sealed.  The heat-exchanger is closed at the top by dome 42 and at the bottom by ring 44.  A body of sea water W, supplied through pipe 24, surrounds the heat-exchanger. Heating-steam is introduced into the interior of the heat-exchanger through conduit 28, and is caused to flow down the inner recesses of the corrugations by inner skirt 46 which is disposed close to the inner bends of the corrugations.  The steam-condensate collects in sump S, and is withdrawn through pipe 30.  The steam evaporated from the boiling sea water passes out through conduit 16, which leads to one or more separating chambers (for the removal of entrained water) and then to a condenser. Concentrated brine is withdrawn from the evaporator via pipe 26. Another embodiment is described which is particularly suitable for use when pulsations in the heating-medium are to be eliminated, e.g. as when hot exhaust gases from an I.C. engine are utilized, or in a distillation system of the vapour-compression type.  Specification 674,385 is referred to.
